ENVELO P.

SPECIFICATION forming part of Letters Patent No. 664,694, dated December25, 1900.

Application filed November 6, 1900. Serial No. 85,621. (No model.)

To (tZZ whom it may concern:

Be it known that I, JAMES A. ULLMAN, a citizen of the United States, anda resident of the city of New York, borough of Manhattan, in the countyand State of New York, have invented a new and Improved Envelop, ofwhich the following is a full, clear, and exact description.

The purpose of this invention is to provide an envelop which may beopened very much more readily than those ordinarily constructed. To thisend 1 form in the sealing-flap of the envelop an orifice through whichmay be inserted the blade of a knife or like instrument to cut open theenvelop, and in order to make it more easy to insert the knife-blade Icut a notch in the back of the envelop just under the opening, so thatthe knife-blade will have a clear passage into the interior of theenvelop.

This specification is a specific description of one form of theinvention,while the claim is a definition of the actual scope thereof.

Referenceis to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a rear view of an envelop unsealed,showing my inventionapplied thereto. Fig. 2 is a view of the envelop sealed, and Fig. 3 is asection on the line 3 3 of Fig. 2.

a indicates the openingwhich is cut in the sealing-flap of the envelop.This opening will not be visible from the front of the envelop, and whenthe envelop is sealed the opening appears as a mere slit in the back orsealing flap.

1) indicates a notch which is cut in the back of the envelop and in suchposition that it lies directly under the opening a when the fiap isclosed, as shown in Figs. 2 and 3.

The envelop thus constructed appears pre cisely the same as an ordinaryenvelop, and it may be very readily opened in the manner explained.

The invention is particularly advantageous when a large amount of mailis to be opened, in which case the letters are generally arranged in apile with the backs upward, and when constructed according to myinvention the envelops may be successively opened with great rapidity.

. By arranging the opening in the flap as shown I minimize thepossibility of accidental tearing of the envelop at pointsv around theopening, because the flap is scaled down all around the opening a, whichlatter is thereby reinforced, and if a tear is started it will beconfined to the immediate vicinity of the opening.

Having thus described my invention, I claim as new and desire to secureby Letters Patent An envelop, havinga flap at the back thereof, whichflap lies'over another part of the back of the envelop, said flap beingformed with an opening, and the said other part of the back of theenvelop over which part the flap lies being formed with a notchregistering with the opening in the flap, and leading toward the edge ofthe envelop which is to be cut, whereby the instrument used in cuttingthe envelop may be entered through the opening and notch andconveniently engaged with the edge of the envelop.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

JAMES A. ULLMAN.
